Gunar industries manufactures a highly sensitive instrument used for detecting feeble noise arising from bearings and gears in machines, automobiles, engines, etc. Even minute noise, which cannot be heard by normal hearing, will be clearly audible. There is an inbuilt indicator in the detector. It can be used for taking different readings for comparison. The bearing & gear noise detector is a battery operated handy type device and hence can be taken to the work spot. It is useful for maintenance as well as quality control purposes.
